DISPENSING AND SEVERING DEVICE FOR ROLLED STRIP MATERIAL.

Application filed May 6,

This invention relates to a dispensing and severing device for rolledstrip of binding material and to an improved roll of strip materialwhich is especially applicable for use therein.

Various forms of dispensing devices for strip material have beenheretofore proposed, their construction being such as to retain a rolledstrip one end of which is projected through an outlet provided in thecusing from which it is drawn in the de ired lengths for use in bindingpackages or the like. Provisions having been made for severing the stripby providing a severing edge at the outlet portion of the casing and insome instances moistening devices have been attached or embodied in thedispensing mechanism whereby the gummed portion of the strip ismoistened as it is drawn through the casing outlet.

In accordance with the present invention the dispensing and severingmechanism is designed to sever the strip of binding material inredetermined lengths and at definite portlons of the strip for reasonsto be hereinafter stated; and it is among the objects of the inventionto provide a dispensing and severing device which shall beof simple anddurable mechanical construction and in which the parts are readilyaccessible for the manipulation of the rolled strip in refilling thedevice and which shall be adapted to maintain the roll in its properworking position in the casing.

Another object of the invention is to provide a dispensing device whichis formed to provide a passage or outlet for the strip, the outer end ofwhich being provided with a severing edge having a tongue projectingthereon which is adapted to engage weakened ortions such as slits orperforations provi ed in the strip at the proper line of severing andwhich shall maintain the strip under suitable tension to preventunreeling and possible damage to the strip Within the casing member.

Still another object of the invention is to provide a dispensing devicewhich shall be interchangeable with its supporting brackets for use as aunit or in multiples as may be desired. v

In the accompanying drawings forming a part hereof and in which likereference characters designate like parts, Fig. 1 is a sectionalelevational view of the dispensing mechanism embodying the principles ofmy in- 1927. Serial No. 189,259.

'7 is a sectional elevation of the outlet chantion of the rolled strip 6when assembled in position.

The casing 1 is provided with a cover portion 7 which is hinged at 8 inthe manner shown. The casing and cover are slightly projected as shownto provide an outlet portion for the strip material which is conductedthrough a passage constituted by the end of the cover 7 and a portion 9of the casing. The cover 7 is provided with an elongated opening 10 inalinement with the passage to make the strip, passing underneath,accessible to the operator who, by engaging it with the finger, canadvance it in the passage to the outlet portion thereof. The cover isfurther provided with a tension device 11 comprising a spring or otherresilient strap which is secured to the cover as by riveting at 12. Anadjustable set screw 13 is provided in the cover, which may be locked inits adjusted position by lock nuts 14 and which functions to depress thetension member 11 against a stop lug 15 which may constitute one of theconnecting bolts of the side walls 2 and which is provided with aferrule or roll 15*. A thumb lug 16 having a screw portion 17 is adaptedto be screwed against the cover 7 to operate as a knob in manipulatingthe cover. If it is desired to adjust the tension screw 13 the lug 16 isremoved by unscrewing the element 17 which renders the lock nuts andscrew accessible for adjustment.

The cover at its free end is provided with pins 20, Fig. 5, which areadapted to be engaged by latches 21, Figs. 1 and at, which aremanipulated by thumb levers 22 within the limits of the slots 23 formedin the cas ing 1. The latch 21in the position shown in Figs. 1 and 4 isin engagement with the pins of the cover and locks the latter in itsclosed position. When the thumb levers 22 are raised the latch 21releases the pins 20 and the cover may be raised on its hinge 8.

Referring to Figs. 3, 4 and 5 of the drawings, the end of the cover 7 isprovided with a severing edge 25 having a downwardly projecting tongue26 located centrally of the passage. A spring element 27 is dis posed inthe passage and is secured to the casing 1 by a rivet 28 at one endtolie in the path of the paper strip 29, Fig. 4, which passes over thespring. The spring 27 is biased to normally urge the strip 29 againstthe tongue 26 of the severing edge so that regardless of the manner inwhich the strip is drawn from the passage it will always engage theunderside of the tongue. The spring 27 is partially exposed in theslotted portion 10 of the cover so that when a strip has been severed atthe edge 25 and it is desired to advance the strip to project it beyondthe outlet, the operator inserts his finger in the slot 10 to engage thestrip thereb exerting pressure against the spring 27 WlllCll displacesit away from the tongue 26 and permits the strip to move in the passageand project beyond the outlet where it is engaged and withdrawn. As thestrip is withdrawn from the dispensing mechanism the spring 27, aspreviously explained, urges it against the tongue 26 and it is obviousthat if a perforation or weak portion is provided in the strip, thelatter will be ruptured by the tongue 26 when the weak portion by theact of withdrawing the strip is brought to register therewith. It is ofcourse obvious that the tongue may be an u wardly projecting portion onasevering e ge formed on the casing and that the strip may be biased aainst it in a suitable manner, instead 0 shown.

Referring to Figs. 6 and 7 of the drawings the strip 29 is held againstthe spring 27 by a strap 35 as follows: The member 35 comprises abifurcated strip of metal turned at one end to receive a pin 36, Fig. 7by means of which it is pivotally mounted on the cover 7 or the casm 1as may be convenlent. The strap 35 y its own wei ht holds the paperstrip 29 against the spring 27, and by projectin substantially to theedge of the spring 2 it functions to prevent the edge of the strip fromcurling when severed. The strip 29 is thereb held flat on spring 27 sothat it may rea ily be advanced without interference by the tongue 26 ofthe severing edge 25.

the construction herein The paper binder strip shown in Fig. 2 isprinted on one side with legends designating the amount of bank notescontained in a given bundle, and its other side is provided with gummedport-ions which are spaced to correspond with the printed matter shownin Fig. 2, and as it is necessary to have the printed matter appear onthe same portion of the binder when it is applied to a bundle, it isessential to sever the strip at or near the gumined portion so that whenthe severed strip is joined by moistening the gummed end the printingwill appear uniformly on all bundles so joined. Accordingly I haveprovided slits 30 at the edge of the gummed portion of the strip and theslit, when the strip passes underneath the tongue 26, will be engaged bythe latter to prevent its further withdrawal from the dispenser. Thiswill of itself effect a severing of the strip in alignment with the slit30 or it will abruptly stop the movement of the stri which indicates tothe user that the point 0 severance has been reached, and by a suitableupward movement of the strip it will be severed at its proper place. Iprefer to use a slit instead of perforations or other means of weakeningthe strip since thereby no material need be punched out in the printingand gumming machine which would clog up the latter and retard the speedof manufacture. The operation of the dispensing and severing device isbriefiy as follows:

The roll of strip material shown in Fig. 2 is assembled in the casing bydispensing the pin 5 in the slot 6 of the side walls thereof and thefree end of the strip is laced between the tension member 11 and the pin15 of the casing and drawn through the passage constituted by the casingportion 9 and cover 7 r to project through the outlet. The cover 7 isthen closed by depressing the pin 22 to lock the latch 21 with the pins20. The strip is then withdrawn from the dispensing device which willhave been previousl set by the adjusting screw 13 to provi e a suitabletension on the strip by the tspring element 11 and as the strip is withrawn from the passage the spring 27 yieldingl urges it against thetongue 26 which w en the slit 30, if the stri ters therewith, projectsthrough t e strip which is severed on the edge 25 at the slit portion.The operator then advances the edge of the strip throu h the elongatedopenin 10 in the cover which depresses the spring 7 and permits thestrip to clear the tongue 26 until it again projects-out of the casing.y

In the use of the dispensing mechanism for binding strips for banknotes, it is someregistimes desirable to have a plurality of rolls Ihave provided for the journalling of the roll pins 5'in the side wallsof the casing to make the latter interchangeable and to adapt them formounting between a single set of end brackets, in the manner of mountinga single unit as shown in Fig. 3. In prior devices of this nature, asingle rod has been projected through all of the supporting wall membersto engage the respectlve rolls contained therein, and this necessitatesthe disturbance of all of the rolls for the renewal of any one of therolled strips.

It is evident from the foregoing description of this invention that thedispensing and severing device for rolled strip material illustrated.and described herein comprises a simple and efiicient means fordispensing and severing the same and particularly provides for thesevering of the strips at predetermined lengths, and in accordance withthe location of the printed and gummed portions of the strip member.
